Excellent condition CASIO G-SHOCK GA-100-1A1JF Black Operation confirmed, no issues. Popular model worn by Beckham. Purchased about 5 years ago. Shows signs of use, but I think it will look good with some care. Please judge the details from the photos. Buttons function well. Alarm and backlight can be used without problems. No box, instructions, or warranty. I have checked, but there may be oversights. If you have any concerns, such as in the images, please feel free to comment. This is a used item, so please refrain from purchasing if you are concerned about minor details or are a nervous person, or if you will leave a negative review for unreasonable reasons. To prevent swapping, returns are not accepted after purchase, so please understand and agree before purchasing. Also listed elsewhere, so it may end early. Thank you.
